The medial lemniscusalso known as Reil’s band or Reil’s ribbonis a large ascending bundle of heavily myelinated axons that decussate in the brainstemspecifically in the medulla oblongata.

The medial lemniscus is formed by the crossings of the internal arcuate fibers. The internal arcuate fibers are composed of axons of nucleus gracilis and nucleus cuneatus. The axons of the nucleus gracilis and nucleus cuneatus in the medial lemniscus have cell bodies that lie contralaterally.

The medial lemniscus is part of the dorsal column—medial lemniscus pathwaywhich ascends from the lemnisvo to the thalamus[1] which is important for somatosensation from the skin and joints, therefore, lesion of the medial lemnisci causes an impairment of vibratory and touch-pressure sense.

Lemniscus means “ribbon”, so named because the medial lemniscus “spirals” or “turns” as it ascends. After neurons carrying proprioceptive ,ateral fine touch information synapse at the gracile and cuneate nuclei, axons from secondary neurons decussate at the level of the medulla and travel up the brainstem as the medial lemniscus on the contralateral opposite side.

It is part of the posterior column-medial lemniscus pathwaywhich transmits touch, vibration sense, as well as the pathway for proprioception. The medial lemniscus lemniscp axons from most of the body and synapses in the ventral posterolateral nucleus of the thalamusat the level of the mamillary bodies.
